Use cases
Applications
- —Flexible wire and cable outer jackets
- —Door and window sealing profiles
- —Extruded sealing and trim profiles
- —Soft-touch cable accessories
Process notes
Processing Recommendations
- —Pre-dry at 80°C for 1–2 h before extrusion
- —Barrel temperatures: rear 170–190°C / middle 180–200°C / front 190–210°C; die 190–210°C; never exceed 240°C
- —Purge the machine thoroughly with PE or PP before and after runs; do not let material dwell hot in the barrel — prolonged heat degrades TPV
